Hall voltage changes with changes in magnetic field strength, the stronger the magnetic field, the higher the voltage, the weaker the magnetic field, the lower the voltage. Hall voltage value is small, typically only a few millivolts, but amplified by the integrated circuit, which can make the output voltage is amplified to a sufficiently strong signal. Hall-effect sensor IC from Ruoshi need to mechanically change the magnetic field strength. The method is shown below with a rotating impeller flux as a control switch, when the impeller blades in the air gap between the magnet and the Hall IC, the magnetic field deviation integrated on-chip, the Hall voltage disappears. Thus the sensor type, the output voltage of the Hall IC sensor quality variation, showing a position sensor can impeller drive shaft, the use of this sensor works classification, can be a Hall effect integrated circuit chip with the ignition timing sensor . Hall-effect sensor is a passive sensor, it must have external power supply to work, a feature that enables it to detect low speed functioning. Linearity: refers to the degree the actual relationship between the sensor output and the input curve between the amount of deviation from the line fit. Is defined as the actual curve and fitting than the maximum deviation from a straight line with the full-scale output value in the whole range. Sensitivity: Sensitivity is an important indicator of the sensor static characteristics. It is defined as the amount of the increment of the corresponding input than output increment increment and cause. S for sensitivity. Hysteresis: The sensor input from small to large (positive travel) and enter the amount of descending (reverse itinerary) during the change of its input-output characteristic curve does not coincide with the phenomenon has become sluggish. For the same magnitude of the input signal, the output signal of the positive and negative stroke sensor size is not equal, the difference between this difference is called hysteresis.
